The energy of an isolated system moving in a straight-line along the x-axis is given by the following equation: E=( 2 kg) Vx^2 -(8 J/m)x. What is the magnitude of the acceleration of this system (in m/s2)?

the given statement is true.

sensory memory lasts for a fraction of seconds before the information is lost. it is the shortest -term memory and can be called as an element of memory. example: when we look at something and remember what it looks like, is just a second of observation. it degrades very quickly. it can also be considered as the process of perception rather than considering it as a memory.
